Some people might assume that customer relationship management (CRM) software and solutions are aimed strictly at large sales forces (no pun intended) at large multinational companies with operating budgets to match. And that’s simply not the case. Whether you’re a company of one or a company of one thousand, sales are what drive your business. And you need to keep tabs on all your leads, prospects and customers alike.

In order to keep up with the agile and dynamic nature of today’s marketplace, entrepreneurs, freelancers and small business owners should look for at least two things in a CRM solution. First, it should be accessible anywhere, as cloud-based solutions are much more versatile and flexible. Second, it should be scalable, growing alongside your business to accommodate your growing needs. All of the services listed below fit these two basic criteria and then some.
